Abstract
Psuedomonas exotoxin 40 is modified by deleting or substituting one or more cysteine residues. Such a modified protein may be incorporated into a fusion protein with TGF.alpha.. The resulting fusion protein exhibits altered biological activities from unmodified TGF.alpha.-PE.sub.40, including decreased cell killing activity and increase receptor-binding activity.
